A prefabricated speed bump and the installation method are provided to arouse a driver's attention when passing by forming a vibrator, to reduce the braking distance of a vehicle by discriminating a speed bump easily on the surface, to prevent the hydroplaning phenomenon in the rain by coupling a frictional force strengthening member, and to re-install a speed bump after removing for arrangement works of water supply and drainage pipes, gas pipes and conduit pipes by separating and coupling a bolt freely, and separating and assembling a speed bump possibly. A speed bump(100) comprises many weight reduction grooves formed on the bottom of a speed bump to reduce the weight of a speed bump, many vibrators(12) arranged on the surface at regular intervals to provoke the shake phenomenon on tires of a vehicle, and a guideline(13) formed in a partition for guiding the location to indicate the color of a speed bump and functioning as a boundary line to attach a reflective lane tape or to paint with reflective paints. |
